Almost everything I print comes out with some dust spec which messes up the print in the area it is in. My machine is clean as far as the print head goes and I tried wiping down the media but I can't get the dust away. Is anyone else having trouble with dust spots, and what can I try to avoid this? The spots are small and doesn't effect the whole print but it keeps it from being perfect, which is what I need it to be if I want to use it in final productions for costumers, unless that is a norm in the business. Any comments and suggestions appreciated.
